Definitions

  • the present invention refers in general to the field of production of vegetable products, for example of horticultural products such as vegetables to be eaten fresh and aromatic herbs or other varieties of plants, by soilless cultivation techniques, as well as to the distribution of said vegetable products aimed at the sale.
  • the invention concerns an aeroponic system for the modular cultivation and transportation of plant products according to the appended claims.
  • the present invention starts from the idea that a cultivation system that is able to allow to pick up a vegetable product from the production site, as well as to transportate it and to expose it for the sale with its root system intact, so as to maintain alive the plant, would allow the final user to have available a product in which the step of decline subsequent to collection is not yet started, so that the vital qualities and the possible organoleptical and nutritive properties thereof remain unchanged.
  • the end user can therefore decide whether it is time to perform the step of collection by removing the root system of the plant, so as to keep an optimum quality of the vegetable product for a relatively long time. This would also considerably limit the waste resulting from deterioration of the vegetable products.
  • the so-called "aeroponic” cultivation technique is particularly suitable for cultivation and transportation of vegetable products for sale to a final consumer.
  • this known technique allows plants to be fed by nebulization means for nebulizing water enriched with mineral fertilizers, which is directly sprayed on the root system of the plants to obtain the growth of the plants in a localized environment without using soil or other granular support materials. Also, exposure of the plants to pests and pathogenic agents is substantially eliminated, and the oxygenation level of the root system of the plants is improved, which favour their development.
  • the “aeroponic” cultivation technique takes advantage of the impact of the air on the plant roots to improve their development and to allow at the same time saving of water and nutrients, because their amount not absorbed directly by the roots can be recovered to be entered again in circulation in the system.
  • US 2012/0085026 A1 is known an aeroponic system for cultivating plants or vegetable products, of the type defined above.
  • This known system comprises a series of containers which may include more container units arranged at different heights, the containers of each unit having the bottom located at the same level.
  • Each container houses inside it a nebulizer unit for nebulizing a nutritional fluid to the roots of the plants, the various containers of the system being connected with a first hydraulic line connected to the delivery side of a pump, which connects in series the containers of each container unit.
  • the suction side of the pump is connected to a tank for collecting the nutritional fluid, which is placed at a lower level and is separated with respect to all the containers of the series, by means of an auxiliary hydraulic line connected to the bottom of all the containers of such a series of containers.
  • a pump for each series of containers is used, as well as a plurality of first nebulization lines and more auxiliary hydraulic lines, which are independent for each series of containers.
  • the object of the present invention is to propose a modular aeroponic system for cultivating, transporting and exposing vegetable products, having a particularly simple structure provided with a relatively small number of components and that allows a reduced amount of nutritional fluid to be used with respect to the aeroponic systems known up to now.
  • the plurality of containers of the system comprises a main container and a series of secondary containers, the bottom of all said secondary containers being arranged at a higher level with respect to the bottom of the main container, said auxiliary hydraulic line being connected only to the bottom of the main container, and said second hydraulic line connecting with each other the bottom of all said containers.
  • the system according to the invention comprises particularly simple hydraulic lines, with the benefit of reducing the manufacturing costs, which also allows separation of the various containers to be made easily in order to transportation them for the exposure in a point of sale of the vegetable products, and to reconnect them equally easily at the point of sale to keep the vegetable products alive up to the time of their pick-up by a final user.
  • the main container performs the function of a collection tank for the nutritional liquid, without any need to provide a separate collection tank, the level of nutritional liquid in the secondary tanks being substantially zero, so that the system requires a minimum amount of nutritional fluid, which allows the water and the amount of the nutritional substances used by the system to be considerably saved.
  • the cultivation system of the invention allows the transportability of the various modules, typically from the cultivation site to the exposure and sale site of the vegetable products, to be made easier, which enables such products to remain in the vegetative phase even during the transportation and exposure steps. In this manner, the collection step of such products is postponed to the maximum, since it takes place only by the end user after purchase.
  • the system of the invention comprises a hydraulic washing circuit that includes a third hydraulic line connected to each of said containers and selectively connectable to the delivery side of the pump.
  • the containers of the system can be washed in a simple and practical manner to be prepared for a new operating cycle.
  • the system comprises ozonization means to ozonize said nutritional fluid, which means are connected to the inside of the main container.
  • the system comprises artificial lighting means arranged above said vegetable products and associated with each of said containers.
  • a first on-off valve is interposed between the delivery side of said pump and said first hydraulic line
  • a second on-off valve is interposed between the delivery side of said pump and said third hydraulic line.
  • first and second on-off valves consist of solenoid valves
  • the operation of said pump and/or of the first and second on-off valves is managed automatically by electronic control means, which allows the pump and/or the first and the second on-off valves to be driven in an optimal manner.
  • the same electronic control means are also susceptible to automatically actuate the ozonization means and/or the artificial lighting means of the system.
  • a modular aeroponic system for cultivating, transporting and exposing vegetable products, is indicated by reference sign 10.
  • the system 10 includes a series of containers arranged side by side, which can be arranged according to a linear configuration shown in Figures 1 , 4 , 7 and 8 or in a flat configuration that extends in the two spatial directions so as to be arranged side by side both longitudinally and transversely.
  • Each of such containers which are generally indicated by the numeral reference 12, consists of a separable and transportable module of the system 10, which allows a plurality of vegetable products or plants 14 to be cultivated.
  • the various container modules 12 have a generally box shape open at the top and are substantially closed by means of a removable upper cover 16 having a plurality of circular openings 18, for example forty-eight of these openings with reference to the figures.
  • Each opening 18 is intended to removably receive a respective pot 20.
  • each cover 16 is divided into four separable sections 16a, which can be removed independently from the respective container 12.
  • Each of the pots 20 has perforated side surface and bottom, in order to constitute a support of the roots system of the plant 14 during its vegetative development, and it allows at the same time its roots to communicate with the inside of the respective container 12.
  • the system 10 comprises a main container indicated 12a, and a series of secondary containers 12b, for example arranged so as to rest on the soil according to a linear series.
  • the bottom of all the secondary containers 12b is located at a higher level with respect to the bottom of the main container 12a, for the purpose which will be explained in the following of the description.

  • a vertical duct 36 extends from each T-shaped fitting 32, which is connected to two curved branches 38 in turn connected to respective parallel linear ducts 40 that extend inside the containers 12a, 12b between a pair of opposite side walls of each container, each of these ducts 40 being provided with a series of nebulization nozzles not shown in detail being of a type known per se.
  • a first on-off valve 42 is interposed between the delivery side of the pump 24 and the first hydraulic line 22, to connect selectively the pump 24 to the first hydraulic line 22, the valve 42 being conveniently constituted by a solenoid valve.
  • a second hydraulic draining line 44 which is separated from the first hydraulic line 22, is associated with the series of containers 12a, 12b to connect the bottom of all the containers 12a, 12b by respective elbow fittings 46.
  • the bottom of all the secondary containers 12b is arranged at a higher level with respect to the bottom of the main container 12a.
  • spacer elements 13 are used, which are arranged below the supporting feet of the secondary containers 12b for raising the latter.
  • the spacer elements 13 can be constituted by blocks of predetermined height, as shown by way of example in the figures, they are preferably of the type adjustable in height and include, for example, screw rest members provided with a threaded shank engaging a nut screw (not shown) connected to the bottom of the respective container 12b.
  • the level of the bottom of the secondary containers 12b can be changed with respect to the level of the bottom of the main container 12a for the purpose that will be clarified in the following of the description.
  • the spacer elements 13 of the adjustable type can be conveniently incorporated in the various support feet of the secondary containers 12b.
  • a duct 48 is connected to the main container 12a only, to connect the inside thereof to an ozonizer device 50 in order to oxygenate, when this is necessary, the nutritional fluid in this main container 12a.
  • the device 50 usually includes its own pump for supplying oxygen to the main tank 12a.
  • artificial lighting means are associated with the various containers 12a, 12b, which are arranged above the plants 14 and comprise one or more lamps 52 for each container, with the aim of integrating or replacing natural lighting, in order to optimize the stage of growth of the plants 14.
  • the system 10 is provided with a hydraulic washing circuit for washing the containers 12a, 12b, which consist of a third hydraulic line indicated 54 in the Figures.
  • This hydraulic line 54 is connected to each container 12a, 12b at a hole 56 formed in a side wall thereof, preferably the side wall opposite to that adjacent to the vertical ducts 36 of the first hydraulic line 22.
  • This washing circuit can be connected selectively to the delivery side of the pump 24 by a second on-off valve 58, conveniently consisting of a solenoid valve, which is interposed between the third hydraulic line 54 and the delivery side of the pump 24.
  • the two on-off valves 42 and 58 are driven electrically by a programmable electronic control unit of the PLC type, in such a manner that when the valve 42 is open, during the normal operation of the first hydraulic nebulization line 22, the valve 58 connected to the third hydraulic washing line 44 is closed.
  • the valve 42 of the first hydraulic nebulization line 22 is closed.
  • the pump 24 and the valves 42 and 58 are connected to the electronic control unit PLC via respective conductor cables 24a, 42a and 58a.

  • the valve 58 is open while the valve 42 is in the closed condition. Water is then fed inside the main container 12a to a preselected level, to start a washing step of the system 10.
  • the third hydraulic line 44 of the washing circuit is in the active condition, while the first hydraulic line 22 of the nebulization circuit is inactive.
  • the pump 24 By operating the pump 24, the water in the container 12a is taken from the latter by the pump 24 through the duct 26, and it is sent to all the secondary containers 12b, in addition to the same main container 12a. Owing to the principle of the communicating vessels, all the containers 12a and 12b are connected to each other by means of the second hydraulic draining line 44, and the water is present in them at the same level.
  • the pump 24 is temporarily deactivated and the washing water in the container 12a is discharged to the outside of the system 10, and with it the water in the secondary containers 12b.

  • the plants 14 have been inserted with their pots 20 into the openings of the covers 16 of the containers 12a, 12b. In this condition, the roots of the plants 14 can absorb the nutrients necessary for their growth, from the inside of the respective containers 12a, 12b.
  • the amount of nutritional fluid fed inside the main container 12a is dosed in such a manner that its level (indicated H in Figure 7 ) is substantially equal to the thickness of the spacer elements 13.
  • its level indicated H in Figure 7
  • this feature is important to ensure a minimum water and nutritive substance consumption by the system 10, and it is of considerable importance for the use of the system of the invention in places where there is little water.
  • the demand for the nutritional fluid to be nebulized inside the various containers of the system 10 is proportional to the number of secondary containers 12b, which can vary with the need, and hence the volume of nutritional fluid in the main container 12a is also variable as a function of the number of secondary containers 12b. Therefore, the greater will be the number of secondary containers 12b, the higher the level of nutritional fluid in the main container 12. Consequently, to make the level of nutritional fluid null in the secondary containers 12b, the bottom of the latter need to be placed at a level at least equal to that of the nutritional fluid in the container 12a, which will be obtained by adjusting the height of the spacer elements 13.
